ROTJ - Extended Luke-Obi Wan scene?

This extended dialogue was probably filmed as it was in the 3rd draft of the script, supposedly.

51 EXT DAGOBAH SWAMP - X-WING 51

Luke wanders back to where his ship is sitting. Artoo beeps a
greeting, but is ignored by his depressed master. Luke kneels
down, begins to help Artoo with the ship, then stops and shakes
his head dejectedly.

LUKE
I can't do it, Artoo. I can't go on alone.

BEN (OS)
Yoda will always be with you.

Luke looks up to see the shimmering image of BEN KENOBI.

LUKE
Obi-Wan! Why didn't you tell me?

The ghost of Ben Kenobi approaches him through the swamp.

LUKE
You told me Vader betrayed and murdered my
father.

BEN
You father was seduced by the dark side of
the Force. He ceased to be Anakin Skywalker
and became Darth Vader. When that happened,
the good man who was your father was
destroyed. So what I have told you was
true... from a certain point of view.

LUKE (turning away, derisive)
A certain point of view!

BEN
Luke, you're going to find that many of the
truths we cling to depend greatly on our own
point of view.

Luke is unresponsive. Ben studies him in silence for a moment.

BEN
I don't blame you for being angry. If I was
wrong in what I did, it certainly wouldn't
have been for the first time. You see, what
happened to your father was my fault.

Ben pauses sadly.

BEN
Anakin was a good friend.

Luke turns with interest at this. As Ben speaks, Luke settles on
a stump, mesmerized. Artoo comes over to offer his comforting
presence.

BEN
When I first knew him, your father was
already a great pilot. But I was amazed how
strongly the Force was with him. I took it
upon myself to train him as a Jedi. I
thought that I could instruct him just as
well as Yoda. I was wrong. My pride has
had terrible consequences for the galaxy.

Luke is entranced.

LUKE
There's still good in him.

BEN
I also thought he could be turned back to the
good side. It couldn't be done. He is more
machine now than man. Twisted and evil.

LUKE
I can't do it, Ben.

BEN
You cannot escape your destiny.

LUKE
I tried to stop him once. I couldn't do it.

BEN
Vader humbled you when first you met him,
Luke...but that experience was part of your
training. It taught you, among other things,
the value of patience. Had you not been so
impatient to defeat Vader then, you could
have finished your training here with Yoda.
You would have been prepared.

LUKE
But I had to help my friends.

BEN (grinning at Luke's indignation)
And did you help them? It was they who had to
save you. You achieved little by rushing back
prematurely, I fear.

LUKE (with sadness)
I found out Darth Vader was my father.

 

They could always reintegrate the scene or present the deleted scene with that line excised like what they did to Red Leader in the ANH:SE.
